mysterious happenings...

Personaly I would check your salinity. If things explode(?) then I would say your salinity is low? Your alk can be as high as 11 -12 Dkh before you will notice anything abnormal. I believe that seawater is around 8 Dkh.

As far as your snails go, I can't offer an opion until I now what your Alk is. Maybe the two are related or maybe other factors are in play, in that perhaps they are short lived like Steve suggests or don't have enough to eat.

Hope this helps.
